I love building, let's just get that out there.
My ground station consists of:
- 7" LCD monitor
- 7" Android tablet running DroidPlanner and Andropilot
- Digital video recorder (DVR) and remote control
- 5.8GHz video receiver (VRX)
- 915MHz telemetry tranceiver
- 5A 12V lead acid gel battery
- Video switch between DVR output and direct from VRX
- USB hub (no longer used for telemetry tranceiver, just a handy powered hub for powering/charging random stuff like phones and cameras)
- Voltage and current display
- Main switch
- Sun hood
The video switch is very useful.
Here's a functional diagram:
I've replaced the Android tablet since this diagram was done. The new tablet doesn't seem to allow the telemetry transceiver to work through a USB hub so now it's connected directly and the hub is just for powering random USB things like my phone which is still useful.
At left: GS showing output from DVR on the LCD screen. The 7 segment display shows the current draw (700mA).
At right: Showing 'pure' VRX output. The 7 segment display shows the voltage (12.1V).
